Working Principle
24VDC input power supplies isolated multi-stage DC-DC power conversion circuits for CPU, analog signal acquisition and communication modules. Differential encoder position signals from hydraulic cylinder linear transducers enter high-speed counter peripheral circuits to convert analog position displacement into digital coordinate data. The PowerPC CPU executes real-time closed-loop PID hydraulic control algorithm combining position setpoint command, actual position feedback and pressure force feedback signals, outputs calibrated ±10 V analog drive signals to MOOG servo valves. Embedded PLC logic processes digital interlock safety signals, synchronizes axis movement sequence and triggers emergency stop upon safety circuit break. All operating data transmits to upper HMI or DCS via CANopen/Ethernet bus.

Installation Requirements
- Install inside IP54 or higher industrial electrical cabinet, vertical DIN rail mounting orientation
- Maintain minimum 30 mm vertical clearance top and bottom for aluminum heat sink natural convection
- Analog signal wiring use individually shielded twisted pair cables, single-point grounding at controller terminal block
- Separate 24VDC power supply dedicated to controller, do not share power circuit with high-current relay loads
- Communication Ethernet/CAN bus cables route isolated from analog servo valve drive wiring
Usage Precautions
- Strictly prohibit operation when cabinet ambient temperature exceeds +55 °C to avoid CPU thermal throttling
- Conduct quarterly encoder signal cable insulation resistance inspection to prevent position feedback drift
- All analog signal cable shielding must connect to controller ground terminal only, floating at sensor end
- Backup Flash EEPROM program data before firmware upgrade operation
- Do not remove analog terminal block while controller is powered to avoid transient signal spike damaging internal ADC chips
